Imagine how difficult it is for him to sort through his collection of headshots and personal photos when his stunning smile framed amongst a sculpted face looks the same age in every picture.

Who could possibly tell which shots belong in the 1989 folder and which are from last week's lunch date? This is a burden that the 49-year-old Lowe and his beaming blue eyes accept as fate.

We don't know how Lowe does it. Sorcery? Expensive creams? Yearly hibernation? Yet, somehow, the actor has remained ageless. This astounding power has allowed Lowe to continually land the parts of younger men, including his recent portrayal of President John F. Kennedy in National Geographic's Killing Kennedy.

Don't think Lowe has uncovered the secret to staying forever young and hunky? Just compare current shots of our wrinkle-repelling friend to stills from his major movie roles of the '80s and '90s, such as Wayne's World and St. Elmo's Fire.

If you remove the feathered mullet and outdated wardrobe, it's hard to put a decade on these photos. You might catch the occasional gray hair or little line, but we suspect Lowe may be adding those himself to keep fans from getting too curious.

After scrolling through Lowe's "then and now" pics, it's hard to believe that the actor will be reaching the half-century mark in March, but the big 5-0 seems to be a small detail to Lowe.
